Oppertus is an independant European research and development team, working since 2001 in number of fields, and now concentrated on 5 main projects.

Popims LensPrinter SAS is a recognized innovator in printing technologies, with hundreds of licensees worldwide.
Specialized in the field of dynamic printing it’s teams innovated strongly to create a new way of printing baptized: selective lenticular printing.

Popims LensPrinter SAS is also marketing all software developped by Popims Software: Popims Animator, PopimsRip, and Popims MoiréGenerator

The Optic-ID technology is now finalized. It is the first impossible to forge signature, the answer to the major security need felt by consumers and businesses, across new services.

Main applications are fighting counterfeiting and document fraud.

Latest improvements of the method enable on-line identification of an individual who is invited to place a Smartphone at different locations around a card. The scenario is impossible to replay.

PullTrax, a completely new mechanical transmission method

This method enables manufacturing automatic stepped gearboxes whose transmission ratio automatically varies according to the transmitted torque.

Applications are numerous : gearboxes and clutches for lorries, cars, scooters, bicycles, ships of all sizes, electricity generation, no wear an no dust braking systems, and in fact all kinds of engines that need to be used at specific ranges of speed to provide the best performance.

The goal is to generate very significant energy savings worldwide, by always running engines under the conditions in which they perform best.

Unlike the variable ratio transmissions of the prior art, this new automatic gearbox produces neither acyclism nor vibration, and provides at all times the best possible performance.

Below is a complete new device enabled by this technology, called the "Engine Downsizer". It's a two speeds automatic transmission, that is most of the time in direct drive (the second gear), but that switches temporarily to the first one in case of mechanical overload or at startup.

All Oppertus technologies are protected by multi-national patents that are pending or delivered in number of countries.
